利用三维计算机图形学再现遗址的原貌，不仅需要几何信息，还需要光学信息。为了使模型具有真实感，通常对拍摄的图像进行纹理映射。然而，这些信息无法从风化或部分毁坏的废墟中获得。传统的图像复原技术有很多种，在小的缺失和裂纹的情况下都能克服，但在没有外围信息的情况下，很难很好地复原受损如此严重的壁画。我们提出了一个图像再现的严重损坏的壁画使用纹理信息提取的另一幅壁画实际上已经恢复的保护者和专家猜测并画出的描图。恢复的图像使用相同的颜料墨水。基于恢复图像的纹理信息和分段跟踪图，我们产生一个恢复图像通过应用纹理扩展到每个段。
Not only geometric information but also optical information is needed to reproduce ruins using three-dimensional realistic computer graphics as they were when those were founded. In order to give a model a sense of reality, it is common to carry out the texture mapping of the photographed image. However such information can not be acquired from either weathered or partially destroyed ruins. While there are various conventional techniques for image restoration, which can overcome in the case of small missing and cracks, it is difficult to restore such a heavy damaged mural painting well when there is no information from the periphery.In this paper, we propose an image reproduction of a heavy damaged mural painting using a texture information extracted from another mural painting which has actually been restored by conservators and a traced drawing which the specialist guessed and drew. The restored image was used same pigment inks. Based on texture information from the restored image and a segmented traced drawing, we produce a restored image by applying the texture extension to each segment.
